Rated 5 out of 5 by from Fantastic I`m a first time hot tub buyer and am beyond pleased with the 8.5. Its beautiful, spacious, and relaxing. The delivery service was outstanding, the guys were very knowledgeable of the product, and took the time to educate me on the maintenance. The entire process from seeing, sales, delivery, and hookup was seamless. It sure turned a once skeptic into a firm believer!

I have an HL8.5 spa being delivered and I want to run the electrical up thru the concrete pad I am having installed. Is there a schematic of the bottom of the spa that shows where the electrical wire (power) access is so I can install the conduit before?

How do I access the pumps? I need to know how to take the panel off.

Asked by: Ozogsmom
The pumps for your spa are located on the front side of your spa. In order to gain access to the pumps, you will have to take off one of the two corners at the front side of the spa. Depending on the year of the spa, this can be done by either removing the black thumb screws or by taking off the screw caps with a screwdriver and then removing the screws underneath. Also depending on the year of the spa, the front panel can be removed by taking off the four screw caps and removing the screws, or there can be 3 clips located on the bottom of the panel on the inside. Simply pull the panel at the bottom and it will come off. The pumps are then located at the base of the spa and are bolted to the frame.

What HP are the pumps in the HL 8.5?

Asked by: snickles
I'm sorry, we are unable to locate that information. The spa contains a single speed and a 2 speed 10A Hybrid Balboa pump. Hopefully that helps!
